How to filter input data of logstash based on date filed?

问题

here is my twitter input tweets

"_source": {
"created_at": "Wed Aug 10 06:42:48 +0000 2016",
"id": 763264318242783200,
"timestamp_ms": "1470811368891",
"@version": "1",
"@timestamp": "2016-08-10T06:42:48.000Z"
}

and my logstash config file which include twitter input plugin filter and output

input {
twitter {
consumer_key => "lvvoeonCRBOHsLAoTPbion9sK"
consumer_secret => "GNHOFzErJhuo0bNq38JUs7xea2BOktMiLa7tunoGwP0oFKCHrY"
oauth_token => "704578110616936448-gfeSklNrITu7fHIZgjw3nwoZ1S0l0Jl"
oauth_token_secret => "IHiyRJRN09jjdUTGrnesALw4DRle35WyX7pdnI3CtEnJ5"
keywords => [ "afghanistan", "TOLOnews", "kabul", "police"]
full_tweet => true
}
}
filter {
    date {
      match => ["timestamp" , "MMM d YYY HH:mm:ss", "ISO8601"]
  }
 }
output {
   stdout { codec => dots }
    elasticsearch {
        hosts => "10.20.1.123"
        index => "twitter_news"
        document_type => "tweets"
    }
}

I want to just get new tweets for example today date is 2016-11-16, then I just want to get tweets that have @timestamp= 2016-11-16 not @timestamp= 2016-11-15 or past days tweets, but with this configuration i get past tweets as well, any one help me to how do this ?

回答1:

the idea here is to use ruby code in logstash config. I propose to use timestamp_ms for comparing date.

First need to convert timestamp_ms to integer
Add today timestamp in ms with ruby

Compare timestamps Here is an example:

mutate {
    convert => {
        "timestamp_ms" => "integer"
    }
}
ruby {
    code => "
        t = Time.now
        today_ymd = t.strftime('%Y%m%d')
        today_timestamp_ms = DateTime.parse(today_ymd).to_time.to_i*1000
        event['@metadata']['today_timestamp_ms'] = today_timestamp_ms
    "
}


if [timestamp_ms] < [@metadata][today_timestamp_ms] {
## past days events
    mutate {
        add_field => { "test" => "past days events"  }
    }
} else {
# today events
    mutate {
        add_field => { "test" => "today events"  }
    }

}
